Attempted to download google Chrome, now get message saying site can't be trusted for google.com, this support page and others. Not all webpages are effected.
Get message saying site can't be trusted, certificate chain problem. Does not happen for all websites. Google.com, facebook, Mozilla help page among others are effected. If I make an exception only shows text on left side for some sites, here and facebook. Attempted to use troubleshooter but could not find some of the things it suggested clicking on.
Chosen solution
unfortunately the fiddler2 issuer in certificates might be a sign of unwanted software present on your pc that is intercepting secure network traffic. please go into the system control panel and uninstall programs like BrowserSafeguard, BrowserSafe, SafeGuard or other software that sounds suspicious and didn't get installed by you intentionally.

afterwards, run a full scan of your system with different security tools like the free version of malwarebytes & adwcleaner.

hello, first please make sure that the date & time is set correctly on your system. if this doesn't solve the issue (or it is already set properly), a possible solution depends on different factors:
- what is the error code shown under technical details on the error page?
in case the error code equals sec_error_unknown_issuer, please attempt to add an exception on the bottom of the error page & inspect the certificate (see the screenshot attached for instructions):
- which issuer information does the certificate contain?
thank you!
